CURT 51180 Echo Mobile Bluetooth Trailer Brake Controller, 7-Way, 1-2 Axles
CURT 51180 Echo Mobile Bluetooth Trailer Brake Controller, 7-Way, 1-2 Axles
  • PORTABLE — Echo installs between compatible vehicle and trailer 7-way RV blade connectors and easily transfers between vehicles without under-dash wiring. The vehicle 7-way must provide active +12V power, ground and turn-signal circuits; a vehicle brake-output circuit is not required. Echo uses the 7-way +12V connection to power the trailer brakes, and this circuit should be fused at 30 amps. Some vehicles require tow/haul mode or trailer load detection before 7-way power activates.
  • SMARTPHONE-READY — Use the OneControl Auto app on iOS 14+ or Android 9+. Enable Bluetooth and location permissions, then pair Echo inside the OneControl Auto app, not through your phone's Bluetooth settings. Keep the app in the foreground for prompt manual-override response and only adjust settings while stationary. OneControl Auto 2.2.0 adds improved larger-font support, fixes an Echo-screen crash on smaller Android devices and includes additional bug fixes.
  • ZERO-TOOL INSTALL — When your vehicle's 7-way already provides the required power and ground, Echo installs without under-dash wiring or tools. The safety strap is stored inside the Echo cap and should be installed before use. With the vehicle running or ignition ON and in Park, plug Echo into the vehicle 7-way first, pair through OneControl Auto, then connect the trailer on a level surface. Flashing yellow indicates 5-8 second calibration; solid green indicates Echo is paired with the trailer connected.
  • HIGHLY RESPONSIVE — Echo uses a triple-axis accelerometer for proportional trailer braking and supports trailers with 1-2 axles / 2-4 brakes. Adjust maximum output and sensitivity for your trailer and load. If Bluetooth communication is lost, the brake controller continues operating at the most recently programmed settings; app-based control and controller notifications require app communication. Always test trailer lights and braking before driving.
  • VERSATILE — Compatible with cruise control, ABS and low-voltage/PWM systems. An existing factory or aftermarket brake controller will not function while Echo is installed. When vehicle hazard lights are active, use the app's Hazard Lights setting to prevent pulsing trailer-brake output. Echo is designed for Bluetooth communication up to 50 ft unobstructed, though actual range can be limited by the phone, vehicle construction and other obstructions.
